Gallardo is in danger of losing his rotation spot after the Mariners called up pitching prospect Andrew Moore, Greg Johns of MLB.com reports.

EDGE Analysis

Gallardo has been fairly ineffective this season, with Saturday's five-run outing summing up his struggles on the season. Due to this, Moore seems to be in line to replace either him or Sam Gaviglio in the rotation moving forward, although the needle appears to be leaning toward Gallardo at this point. No official word has come out yet, but Gallardo's upcoming start against the Tigers may be his last chance to salvage a starting role in Seattle.
